[mce hardware error] on a brand new system running 3900x

[ec911]

Hi! I am new in this community and this is my first post.

 

I've been running unraid on trial on my old i7-4970k system without any issues.

I then recently upgraded my system (and bought a Plus license) for a Ryzen 3900x running on a Gigabyte Aorus Elite x570 with 32gb of ram (Kingston Fury 3200mhz)

 

Everything seemed to be ok, I refered to a post on this forum for tips and tricks on this particular motherboard to passthrough gpu for vms.

 

2 days ago, I woke up and server was frozen. Rebooted everything and I started to get Machine check events from Fix Common Problems plugin.

Everything seems to be running fine, but the error keeps coming back. Unless I miss something, can anyone help me out with the error? Is this common on newer Ryzen CPU running on unRaid?

 

I'm running version 6.8.1.

No, that isn't normal. What all have you changed in the bios? If you've messed with overclocking or any advanced settings I would highly recommend setting to factory defaults and making ONLY these changes:

UEFI / BIOS Settings:

Tweaker -> Advanced CPU Settings -> SVM Mode -> Enable

Settings -> Miscellaneous -> IOMMU -> Enable

Settings -> AMD CBS -> ACS Enable -> Enable

Settings -> AMD CBS -> Enable AER Cap -> Enable

 

My initial guess is it is related to Global C-state Control. The factory default settings should be very stable (zero crashes). If you get crashes with default + the above settings, my next guess would be a hardware failure.

 

What power supply are you using?

The only change I've made along with the changes you've mentionned was to turn on XMP profile 1 to clock the ram to 3200 mhz. I put it back to 2400 mhz after but the error happened again. I didn't overclock the cpu.

I'm running a Corsair RM850w. Couple months of use. I was using it on my other system without any issue.

 

 

I will try to replace the ram if the error comes back with the default clock settings in bios.

 

Here's the log that I was getting:

I also noticed this but I don't know what it is
